A small sample of helium occupies 6mL at a temperature of 200K at what temperature does the volume expand to 9mL

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

What does the law of conservation of mass state?

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
